Outside of the Nutanix, I have a Nortel 48 port GE switch, Unifi UAP-AC-LR AP's(2), Unifi cameras(3). I also run a 18TB Unraid server for the bulk storage. The top R710 is a Windows Server I use for running Handbrake.

I've been in the business for about 25 years. Over that time I've made a point of offering to take equipment to the dumpster/recycler whenever it's been ethical to do so. That cabinet was a company that was closing down and was literally going to throw it out. Got a friend with a pickup and we loaded it up. It was a bit challenging to get it in the basement, but when you take the sides and doors off it's not too heavy. Now that it's down there, it's probably never moving. My current problem (pun intended) is the power. The older, smaller UPSs aren't up to the task. If I get a power blip at all, they bounce. UPSs cost money, though. It's fine for the house, even though it's not great for the WAF when Plex is offline. I've been able to test how CE recovers from abrupt power outages! No problems, so far...

I'm having issues getting CE to see the drives connected in my R610.. did you do anything special to get it to see the drives behind the RAID controller?

Yes! Sorry, I didn't get an alert on this thread being updated. I'm running the drives in RAID0 configuration behind an H700 controller. Because of that, CE can't detect the type of drive. You need to manually set the "rotational" drive and then it works fine.

Get to the initial install login, but instead of logging in as install, login as root.

Then, "dmesg | grep sda" to find the HDD. You may have to go through sdb, sdc... to find the HDD. Once you know which drive is the HDD and not the SSD, run the following:

"echo 0 > /sys/bloc/sd?/queue/rotational" with the correct sd letter in place of the ?

logout, then login as install. It should discover the disks correctly from there.
